Generate error codes and messages
AI creates 10 consistent error codes with clear, user-friendly messages.
Generate error codes and messages
River's Error Code Generator creates consistent, well-structured error codes and messages for your application. You provide context, and the AI generates 10 error codes with clear messages, suggested HTTP status codes, and resolution guidance. Perfect for standardizing error handling across your codebase.
Unlike random error messages, we create systematic error handling. The AI understands error code conventions (descriptive codes, actionable messages, appropriate status codes), maintains consistency, and writes messages that help users and developers understand and resolve issues.
This tool is perfect for backend developers building APIs, teams standardizing error handling, technical leads defining error conventions, and projects needing consistent error documentation.
What Makes Error Codes Effective
Error codes succeed when they help diagnose and resolve issues quickly. Effective error codes are descriptive (not just numbers), consistent in format, paired with clear messages, include appropriate HTTP status codes, and provide actionable guidance. Good errors help both users understand what went wrong and developers debug issues efficiently.

Frequently Asked Questions
Should error codes be numeric or string-based?
String-based codes like USER_NOT_FOUND are more descriptive than numeric codes. They're self-documenting and easier to understand in logs. Numeric codes require looking up meanings. Use descriptive strings for better developer experience.
What's the difference between user messages and developer messages?
User messages are customer-facing (simple, non-technical). Developer messages include technical details (stack traces, variable values). Show users what they can do. Give developers what they need to debug. Separate the two for best experience.
Should I expose internal error details to users?
No. Users get friendly messages. Developers get detailed errors in logs. Never expose database errors, file paths, or stack traces to users. Security risk and poor UX. Log detailed errors, show friendly messages.
